I'm ok with the cuteness factor of the 450b. I just think they should
offer a full 2 footer also. Yeah the 450i + a dish + jumpers has got to
be $700-$800.
I wonder if it's the same marketing error as New Coke. In testing 2/3's
of customers preferred the new formula. Fuck the other 1/3, they don't
matter.

They are discontinued, Cambium stopped making them around the

that’s “fake news”. Actually I would have to check the spec sheet but
I thought they were claiming 23 or 24 dBi.
It seems to be part of a strategy of sharing designs with ePMP but
charging more.
Customers do seem to like the aesthetics of the 450b dish. Swapping
for left-of-pole mounting is a giant pain, especially after you’ve
attached the radome. And installers complain about not being able to
see the lights. What’s strange is we still use reflector dishes for
the 3 GHz SMs.
FWIW, we have solved performance issues with the 450b high gain by
swapping in a connectorized SM and one of the KP 2 ft Proline dishes,
but that’s a big and godawful expensive solution. Strangely the
performance increases more than you’d expect from the signal level
alone, maybe some kind of sidelobe issue?

i was told theyre not discontinued, just not favored and then
something about the 22 vs 25 being a better 22 than the 25 or
something for geeks

Okay I haven't paid a lot of attention to PMP450 since I've been in a
Telrad shop for a few years. It looks like the old style SM was
discontinued.
The Old SM + Reflector was said to have 25dbi of gain.
The replacement 450b "high gain" integrated dish is 22dbi.
Are you kidding me? Cambium, why you takin' my db's away bro?
